The Working Principle of a Quiet/Silent Air Compressor
A quiet/ silent air compressor is specially designed to run quietly, and it is fully automated and almost noiseless. This type of compressor combines machine precision, extra noise insulation, and effective lubrication to absorb most of the noise that might be produced. This makes a quiet compressor an environmentally friendly tool, and it is primarily designed for use in enclosed spaces where a quiet running is preferred. For apparent reasons, any compressor operating at high volume levels would be unwelcome in any work area where people need to use the machine throughout the day.
A machine is considered to be a quiet compressor if it has an operating decibel of less than 75 dB. But this doesn't mean it won't produce any noise. It will still produce some sounds, but the volume will be very low. Just like most compressors, silent air compressors include both portable and static versions. Also, the models come in different tank sizes, weight, horsepower, and operating pressure.
The working Principle of a Silent Compressor
A silent air compressor is designed with noise insulation features, and the periphery is designed with a cover, which helps to dampen the sound immensely. And just like other compressors, you will have the option of choosing a silent compressor with one stage or dual stage belt-driven mechanism for delivering a jet of compressed air.
However, inside the compressor, you will have noise-reducing forms that help to prevent sound transmission from one part of the system to the other. Externally, a silent compressor will have an extra noise-insulating cover that helps to cut out any noise that may have escaped from the parts moving inside. Besides, a quiet compressor is built with high quality (thick and dense) materials to help the machine produce less noise than usual.
Other features that may make a compressor runs quietly includes having a transparent oil level indicator to help prevent unwanted noise during routine checks and maintenance. Also, most quiet compressors piping systems come with sound and vibration insulators to help reduce the amount of sound coming from there.
Silent compressors come in two different varieties, including oil-free quiet compressors and oil-lubricated air compressors.
Design of an oil-lubricated quiet Air Compressor
An oil-lubricated quiet compressor comes with an internal coated air tank, air filter, pressure switch, and pressure switch. However, it is designed with specially formulated air compressor oil that enables the compressor to absorb any moisture.
The coated air tank helps to prevent rust for durability and added consistency. And just because the pump is lubricated doesn't mean the air compressor cannot be used in places where very clean air supply is needed. The piston is fitted with oil filters, which helps to remove oil traces it the air tank.

Design of an oil-free Silent Air Compressors
Unlike the oil-lubricated design, an oil-free air compressor comes in an oil-less design that features innovative air dryers units. The design also consists of internal coating, coalescent filters, and an after cooler to help ensure high air output. The selling point of these compressors is the high-efficient filters that provide clean air for improved air quality and less maintenance.

An air compressor is an invaluable tool to have around, and it can be used for a whole range of things. However, some can get so noisy, especially when used in enclosed spaces. The easiest solution is to buy an ultra-quiet machine that is designed for quiet operation, so it is important to check how loud a compressor is before you decide to buy one.
However, there are some effective ways you can use reduce noise in your existing compressor into something that is quite and a bit easier on the ears. So it is really a trade-off; the amount of money you wish to spend to buy a quiet compressor or modify the existing compressor to lower the volume of low level.
